Optimization of Jaw Crusher
used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Large scale crushing operations are generally performed by mechanically operated equipment like jaw crushers, gyratory crusher and roll crushers.

Four tips for optimising jaw crusher performance |
Larger feed has a negative impact upon the crusher's capacity and reduces its efficiency. Typically, the maximum fed size is roughly 80% of the feed opening depth. Removing the fines from the feed before it's passed to the crusher avoids accelerated wear of the jaw dies and increases the crusher's performance.
